TERROSEAL SBR PWP

TERROSEAL SBR PWP

Styrene Butadiene Rubber Based Polymeric Waterproofing System

Product Description

TERROSEAL SBR PWP is a high-performance, flexible, elastomeric cementitious waterproofing system designed for multi-area waterproofing applications. It is specially formulated to provide long-lasting waterproof protection, superior bonding, enhanced flexibility, and durability for both new constructions as well as repair and renovation works.

TERROSEAL SBR PWP is suitable for waterproof coatings and as an additive in waterproof mortars. It delivers reliable watertightness, excellent adhesion, and strong resistance against water pressure and weathering conditions.

Features & Benefits

  • Two-component waterproofing system

  • Does not require separate primer coat or protective coat

  • Solvent-free formulation for easy application

  • Can be applied on dry as well as slightly damp surfaces (not waterlogged)

  • Forms a very tough and durable coating

  • Excellent abrasion resistance; suitable as exposed coating

  • UV resistant coating

  • Can sustain high water head pressure

  • Ideal for treatment of large continuous waterproofing areas

  • When used with reinforcements, absorbs substrate movement and cracks

  • Protective screeds can be eliminated when used with reinforcement mesh

  • Reduces thermal absorption on terraces resulting in cooler ceilings

  • Saves time, material, and application cost

  • Prevents paint peeling caused by damp walls

Areas of Application

  • Terraces & Roof Waterproofing

  • Swimming Pools

  • Water Tanks (including potable water tanks)

  • Elevated Storage Reservoirs (ESR)

  • Underground Storage Reservoirs (UGR)

  • Bathrooms & Wet Areas

  • Balconies & Sunken Slabs

  • Retaining Walls

  • External Walls & Dampness Treatment

Application in Waterproof Mortars

TERROSEAL SBR PWP is specially designed for waterproof cementitious mortars prepared using:

  • Natural sand

  • M-sand

  • Crushed sand

  • Washed sand

It provides excellent bonding, waterproofing performance, homogeneity, and workability.

For cementitious mortars based on M-sand or crushed sand, use 100–200 ml of Terroseal Super IWP along with 800–1000 ml of TERROSEAL SBR PWP for improved workability and waterproofing performance.

Surface Preparation

  • Clean the surface thoroughly using wire brush and suitable degreasers.

  • Remove dust, oil, grease, loose particles, algae, and contaminants.

  • Use TERROSEAL XRG for best degreasing and surface preparation results.

  • Make the surface smooth and sound before application.

Crack Treatment

  • Seal cracks larger than 1.0 mm using TERROSEAL ALL SEAL.

  • Minor cracks may be directly grouted using TERROSEAL SBR PWP slurry.

Mixing Procedure

Add:

  • 10–12 kg TERROSEAL SBR PWP to

  • 10–15 kg OPC Cement

Recommended Ratio for Best Results

  • 15 kg OPC Cement : 10 kg TERROSEAL SBR PWP

Volumetric Ratio

Use ordinary measuring cups:

  • 6 cups TERROSEAL SBR PWP : 7 cups Cement

(Use the same container for measuring both materials.)

Important

  • Do not add additional water to the mix.

  • Stir vigorously until a lump-free consistent slurry is obtained.

Application Method

  1. Damp the surface properly but avoid waterlogging.

  2. Allow sprinkled water to seep into the concrete surface.

  3. Apply prepared TERROSEAL SBR PWP slurry using brush on RCC surface.

  4. Minimum 2 coats are recommended with an interval of 12 hours between coats.

  5. Cross coating application gives best results.

  6. Cure for 7 days by sprinkling water on the coating.

For Vertical Surfaces

If protective screed or plaster is to be applied:

  • Sprinkle silica sand on the top wet coat for mechanical keying.

TERROSEAL SBR PWP has excellent receptivity for further plaster or mortar applications and provides strong bonding with subsequent layers.

Reinforced Waterproofing System

For terrace and water tank waterproofing systems requiring life expectancy of 10–25 years, use:

  • TERROSEAL FG Reinforcement Mesh
    along with

  • 3 coats of TERROSEAL SBR PWP + Cement slurry

Use as Waterproofing Additive

TERROSEAL SBR PWP enhances:

  • Compressive strength

  • Flexural strength

  • Flexibility of cementitious mortars

It is highly suitable for:

  • Plaster

  • Ghotai

  • Brick Bat Coba

  • IPCC

  • Crushed sand waterproof mortars

Recommended Dosage

Use:

  • 200–1000 ml TERROSEAL SBR PWP per bag of cement

Apply and cure as per standard practice.

Damp Wall & Paint Protection Application

If plaster work is completed, apply TERROSEAL SBR PWP before putty application to prevent:

  • Paint peeling

  • Damp patches

  • Moisture-related failures on walls

Apply putty within 20–45 minutes after coating TERROSEAL SBR PWP.

Product Properties

TERROSEAL SBR PWP is:

  • Non-corrosive

  • Non-toxic

  • Chloride free

  • Alkaline in nature

making it highly suitable for all waterproofing applications.
